[Investigation scene, Deal with the Devil] (2)

Head to the west side of the manor. Eliminate the Lethian and medium squat wylebeast.

Interact with the summoning sigil on the wall by the boarded-up front door.

Go to the south side of the manor and interact with the dead body to collect 'Yellow King's gang casualties' (Evidence 1/5).

Use Mind's Eye to follow omens to the manor's back door on the east. Dispel the illusion on the bricked-up door and enter.

Upon entering, eliminate the two Stygian Harvesters and two Lethians.

Interact with the door marked with the EOD symbol ('Dagon's Eye').

Use Mind's Eye omens to find a blank wall under the stairs in the basement.

Navigate to the basement and avoid the summoning sigil on the floor, which spawns an Acheronian.

Use Mind's Eye on the wall under the stairs to dispel the illusion and access the subbasement.

In the subbasement, go to the ritual altar and interact with the worktable to find 'Ritual workbench' (Evidence 2/5).

Interact with the journal on the altar to find 'Ebernote's ritual' (New Mind Palace Clue) and 'Ritual log' (Key Evidence 1/7).

Interact with the revealed key and examine the EOD symbol on it to find 'Manor key' (Key Evidence 2/7).

Interact with the gold nugget and use Mind's Eye to concentrate on the vision of the past, revealing 'Ritual focus vision' (Key Evidence 3/7).

Approach the wall symbol (diamond with inverted question marks) and use Mind's Eye to dispel the illusionary wall. Interact with the freshly turned earth to find 'Burial' (New Mind Palace Clue) and 'Fresh grave' (Key Evidence 4/7).

In the Mind Palace, combine 'Ebernote's ritual' and 'Burial' to deduce 'Ebernote's rituals were lethal'.

Enter the Retrocognition vision by the altar. Find and mark the three critical scenes in chronological order: 1. outside the ritual area, 2. near the altar, 3. near the fresh grave.

After the vision, you will receive 'A focus from Cthygonnaar' (New Mind Palace Clue) and 'Conclusion' (Key Evidence 5/7).

Follow Mind's Eye omens to the office on the top floor.

In the Mind Palace, combine 'Ebernote has the Seal' (assumed clue from previous investigation) and 'A focus from Cthygonnaar' to deduce 'Ritual has been improved', 'Rituals are doomed to fail', or 'Ritual could save me'.

Go to the top floor and eliminate the three medium squat wylebeasts.

Enter the office in the back. Use Mind's Eye on the coral encrusted stone vase to dispel the illusion and interact with the journal to find 'Place of Pilgrimage' (New Mind Palace Clue) and 'Blackwood's diary' (Key Evidence 6/7).

Interact with the painting of the sea in the bedroom ('Painting of the sea', Evidence 3/5).

Return to the locked Dagon door, enter the small room, and interact with the portrait of Ionia Blackwood ('Portrait of Ionia Blackwood', Evidence 4/5).

Interact with the letter on the table to find 'Ebernote was thought to be Chosen' (New Mind Palace Clue) and 'Letter to I. Blackwood' (Evidence 5/5).

Interact with the print under the book and examine its back to find 'Blackwood Exodus' (New Mind Palace Clue) and 'Come unto the sea!' (Key Evidence 7/7).

All Key Evidence and All Evidence are now collected.

In the Mind Palace, combine 'Place of Pilgrimage' and 'Blackwood Exodus' to deduce 'Finding the cannery'.

Leave the manor grounds.
